<P>PROBLEM TO BE SOLVED: To provide a method of preventing the contamination of a high specific gravity substance in collecting a low specific gravity substance after a separation operation for a centrifugation method separating the high specific gravity substance and the low specific gravity substance from a mixture thereof. <P>SOLUTION: The centrifugation method carries out centrifugation operation in the presence of the melted matter of thermoreversible gelling agent or thermoreversible gel to form a thermoreversible gel layer which separates the low specific gravity substance and the high specific gravity substance. By using the centrifugation method, the contamination of the high specific gravity substance into the low specific gravity substance can be prevented easily. <P>COPYRIGHT: (C)2012,JPO&INPIT |
